Can you use compression fittings on steel pipe?

Compression fittings are not recommended to be used with steel tube. When using compression fittings with any type of plastic tubing, a brass insert must be used for further support. Compression fittings come in a variety of sizes and part numbers.

Can copper compression fittings be used for compressed air?

Copper. Copper piping is an excellent choice for use with air compressors. Any condensation that builds up in the system will not corrode copper air compressor lines, so the risk of debris entering the system is very low. It also withstands heat well.

How do you connect copper to stainless steel?

Yes copper and stainless steel can easily be soldered or brazed together using a filler material that usually contains tin and silver . Unlike welding were we melt the two metals together, brazing or soldering use a filler material to bond the two parts together without melting them.

Are copper compression fittings reliable?

Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems. In general, compression fittings are not as resistant to vibration as soldered or welded fittings. Repeated bending may cause the ferrule to lose its grip on the tube.

Can compression fittings be used on refrigerant lines?

Advice for Making Flare Fitting Connections with Copper Tubing or Piping. Watch out: in our OPINION (and that of other HVAC technicians) compression fittings should never be used and in best practice flare fittings should also not be used on refrigerant gas or liquid piping.

What is the most common cause of leaking compression fittings?

Over tightening is the most common cause of a leaking compression fitting.

What type of copper is used for compressed air?

Copper pipe is a common selection for sensitive compressed air systems and when correctly sized and connected is very durable and effective. Type M hard, type L hard and type K soft copper has a working pressure of 250 psig (17 bar). Type K hard copper is rated for 400 psig (27 bar).

What kind of pipe is best for compressed air?

Ideal plastic pipes for piping compressed air are made of acrylonitrile butadiene styrene (ABS). Polyethylene (PE) piping and high-density polyethylene (HDPE) piping are also good choices for compressed air applications. PVC is not recommended and is an OSHA violation if used.

Can you connect copper and stainless steel?

When connecting copper to stainless steel, a brass or bronze fitting between the two metals provides sufficient electrical separation in most environments. The relative size of dissimilar metals also affects galvanic corrosion. A small, more noble (cathode) component in a system is usually acceptable.

Can stainless steel fittings be used with copper pipe?

While stainless steel is a common plumbing material for water mains and fittings because it has an exceptionally long lifespan and is resistant to corrosion, it’s not a good idea to directly connect stainless steel to copper. This is because stainless steel and copper are actually dissimilar metals.

Why do my compression fittings leak?

Over tightening a compression fitting can also cause the fitting to leak. When tightening up the compression fitting, only turn your tool until you feel resistance. From there, you shouldn’t turn it anymore than a half a turn. By doing this, you can ensure you’ll prevent your compression fitting from leaking.

Can you use compression fittings on copper tubing?

View information about how to measure threaded and unthreaded pipe and pipe fittings. With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings. Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

What is a compression fitting?

It is this radial compression that creates the leak tight seal between the fitting, ferrule, and tubing, and gives the compression fitting its name. The success of compression fittings in a given application can depend on a number of factors.

What does alcohol do to compression fittings?

The alcohol will lubricate the stainless steel surfaces during assembly, and then evaporate completely, leaving no residue or contaminants behind. Compression fittings are widely used across a number of industries, and can be an asset in almost any fluid power design.

Which compression fittings are best for high pressure applications?

Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10,000 psig.
